 *  Arduino Leonardo or other 32u4-based boards (e.g. Adafruit Feather) WITH CAVEAT: USB Serial connection is clobbered on sleep; if sketch does not require Serial comms, this is not a concern. The example sketches all print to Serial and appear frozen, but the logic does otherwise continue to run. You can restore the USB serial connection after waking up using `USBDevice.attach();` and then reconnect to USB serial from the host machine.
 *  Partial support for Teensy 3.X and LC (watchdog, no sleep).
